29 CHIP COIL Large Current Choke Coil LN6C/LS66C Series Choke Coil for DC/DC Converters and DC Power Lines with Low DC Resistance, Large Current Capacity and Large Inductance The LN6C/LS66C series are choke coils which have achieved low direct current resistance, large current capacity and large inductance by using high performance thick wire wrapping technology. Because the LS66C series has a shielded construction, it can be mounted in high density without interference occurring between peripheral components. They are optimum for use as choke coils in DC/DC converters and DC power supply circuits. cfeatures. Both the LN6C series with its open magnetic path construction and the LS66C series with its magnetic shielding construction allow application to a wide variety of uses. 2. The inductance range covers from 0.2 µ H up to 00 µ H allowing minute compatibility with the E6 series at µ H to 0 µ H. 3. Because the direct current resistance is small as well as the voltage drop and power consumption being small also, they are optimum for use as choke coils for DC power supply circuits.

33 Notice of Chip Coil 2. Mounting Instructions q Land Pattern Dimensions Large lands reduce of the mounted chip. Also, large protruding land areas (bordered by lines having dimensions c and d shown below) cause floating and electrode cracks. r Amount of Solder Paste Excessive solder causes electrode corrosion, while insufficient solder causes low electrode bonding strength. Adjust the amount of solder paste so that solder is applied as shown below. Land Solder Resist c LH/LN LS d w Magnetic Coupling Since some chip coils are constructed like an open magnetic circuit, narrow spacing between coils may cause magnetic coupling. (Please refer to Page 37 for coil-to-coil spacing and coupling coefficient.) The LS and LG series have a magnetically shielded structure. The structure makes their coupling coefficient smaller than that of conventional chip coils. In particular, the LS33N series has a very small coupling coefficient. Magnetic Coupling LP/LG Standard thickness of solder paste : 200 to 300 µ m (LG Series,LPA : µ m,lpa/2a : µ m to 50 µ m) t Amount of Adhesive If too much adhesive is applied, then it may overflow into the land or termination areas and yield poor solderability. In contrast, if insufficient adhesive is applied, or if the adhesive is not sufficiently hardened, then the chip may become detached during flow soldering. Apply the adhesive in accordance with the following conditions.,,, e PCB Warping Arrange chip coils to minimize stress caused by PCB warping.

34 Notice of Chip Coil 3. Standard Soldering Conditions q Soldering Method Chip coils can be flow or reflow soldered.(ls33n, LS66C and LPA/2A should only be reflow soldered) Please contact Murata regarding other soldering methods. The volume of solder can cause minor fluctuations in inductance value. Therefore, carefully control the amount of solder when soldering the LPA/2A and LGA series. w Soldering Temperature and Time Solder within the temperature and time combinations indicated by the slanted lines in the following graphs.

Do not directly touch the ceramic element with the tip of the soldering iron. The reworking soldering conditions are as follows. Time (sec.) e Solder and Flux Solder: Use H60A, H63A, (JIS Z 3282) or equivalent. Use solder paste equivalent to H60A for LPA/A/2A and LGA. Flux : Use rosin-based flux, but not strongly acidic flux(with chlorine content exceeding 0.2wt%). Soldering iron power output : 30W max. Temperature of soldering iron tip : 280 C Diameter of soldering iron end : 3.0mm max. Soldering time : within 3 sec. 32

35 Notice of Chip Coil 4. Cleaning The following conditions should be observed when cleaning chip coils. q Cleaning Temperature: 60 C max.(40 C max. for CFC alternatives and alcohol cleaning agents) w Ultrasonic Output:20W/R max. Duration: 5 minutes max. : 28 to 40kHz Care should be taken not to cause resonance of the PCB and mounted products. e Cleaning Agent The following cleaning agents have been tested on individual components. Evaluation in complete assembly should be done prior to production. a) CFC alternatives and alcohol cleaning agents Isopropyl alcohol(ipa) HCFC-225 b) Aqueous cleaning agents Surface active agent(clean Thru 750H) Hydrocarbon (Techno Cleaner 335) High grade alcohol(pine Alpha ST-S) Alkaline saponifier(aqua Cleaner 240-cleaner should be diluted to 20% using deionized water.) LH,LS series:aqueous agents should not be used because they may cause quality deterioration. r Ensure that flux residue is completely removed. Component should be thoroughly dried after aqueous agents have been removed with deionized water. For additional cleaning methods, please contact Murata. 5. Resin Coating When coating products with resin, the relatively high resin curing stress may change inductance values. For exterior coating, select resin carefully so that electrical and mechanical performance of the product is not affected. 6. Caution for Use This item is designed to have sufficient strength, but handle with care not to make it chipped or broken due to its ceramic structure. LH/LN Series Sharp material, such as a pair of tweezers, shall not touch to the winding portion to prevent the breaking of wire. Mechanical shock should not be applied to the products mounted on the board to prevent the breaking of the core. LP Series The pattern of the chip coil is covered withe the protection film. But the handling the chip coil shall be taken care so that the chip coil would not be damaged with the pick-up nozzle,the sharp substance and so on. LG 2N/2C Series There is possibility that the inductance value change due to magnetism. Don't use a magnet or a pair of tweezers with magnetism when chip coil are handled. (The tip of the tweezers should be molded with resin or pottery.) 7. Handling q Avoid applying excessive stress to products to prevent damage. w Do not touch winding with sharp objects such as tweezers to prevent wire breakage. e Do not apply excessive force to products mounted on boards to prevent core breakage. 8. Operating Environment Do not use products in corrosive gases atmosphere such as chlorine gas, acid or sulfide gas. 9. Storage Requirements q Storage Period Products should be used within 6 months of receipt. Solderability should be verified if this period is exceeded. (LH,LN series should be used within 2 months.) w Storage Conditions a) Store products in a warehouse in compliance with the following conditions: Temperature : e to 40 C Humidity : 30 to 70% (relative humidity) Do not subject products to rapid changes in temperature and humidity. Do not store them in corrosive gases atmosphere such as one containing sulfurous acid gas or alkaline gas. This will prevent electrode oxidation which causes poor solderability and possible corrosion of coils. b) Do not store products in bulk packaging to prevent collision among coils which causes core chipping and wire breakage. c) Store products on pallets to protect from humidity,dust, etc. d) Avoid heat shock, vibration, direct sunlight, etc.. Transportations Do not apply excessive vibration or mechanical shock to products. 33
