REMINDERS FOR USING THESE PRODUCTS
Before using these products, be sure to request the delivery specifications.
SAFETY REMINDERS
Please pay sufficient attention to the warnings for safe designing when using these products.
REMINDERS
The storage period is less than 12 months. Be sure to follow the storage conditions (Temperature: 5 to 40°C, Humidity: 10 to 75% RH
or less).
If the storage period elapses, the soldering of the terminal electrodes may deteriorate.
Do not use or store in locations where there are conditions such as gas corrosion (salt, acid, alkali, etc.).
Before soldering, be sure to preheat components.
The preheating temperature should be set so that the temperature difference between the solder temperature and chip temperature
does not exceed 150°C.
Soldering corrections after mounting should be within the range of the conditions determined in the specifications.
If overheated, a short circuit, performance deterioration, or lifespan shortening may occur.
When embedding a printed circuit board where a chip is mounted to a set, be sure that residual stress is not given to the chip due to
the overall distortion of the printed circuit board and partial distortion such as at screw tightening portions.
Self heating (temperature increase) occurs when the power is turned ON, so the tolerance should be sufficient for the set thermal
design.
Use a wrist band to discharge static electricity in your body through the grounding wire.
Do not expose the products to magnets or magnetic fields.
Do not use for a purpose outside of the contents regulated in the delivery specifications.
If an ultrasonic process is used, thoroughly check the condition setting in order to prevent disconnection.
Do not clean the products with solvents. If a potting resin or a moisture-proof coat containing a solvent such as acetone, toluene or
xylene is used, consult with us in advance.
The products listed on this catalog are intended for use in general electronic equipment (AV equipment, telecommunications

Transponder Coils
Overview of the TPL Series
FEATURES
Common in the series
Transponder coils that ensure high reliability suitable for automotive applications. TPL802727 type coils also realize a small size (8 mm
in length) and high inductance (18.52mH max.)
Achieves stable electrical characteristics due to their high SRF design structure.
TPL802727 type
Ensures high reliability suitable for automotive applications by adopting higher heat resistance wire and welding wire connection.
TPL1183427, TPL1183525 types
It is fully resin-molded.
Terminals are highly reliable with the spring structure. They show excellent quality especially in bending and drop resistance.
APPLICATION
Mainly receiving LF antenna coils for the in-car devices shown below
Tire-pressure monitoring system (TPMS)
Keyless entry system
Immobilizer etc.
Other electronic devices
