FEATURES
• TDK has optimized the characteristics of ferrite cores for high
frequency operation and has designed multilayer printed coils
with optimized pattern designs. This has resulted in low
insertion loss and low leakage inductance. The PLT and PLC
series attains high efficiency as well as light weight and small
size.
• While maintaining reliability of the electrical connection between
each layer of the printed coil and the L-shaped header terminal,
the structure of these PLT/PLC series products also allows easy
checking of soldered connections after board mounting.
APPLICATIONS
• While only 5mm tall, this miniaturized planar transformer/planar
choke coil combination also has a greatly reduced footprint.
• Shielding of the printed coil by the core has greatly reduced
noise.
Low-profile DC to DC converters for exchange switchboard power
supplies, low-profile DC to DC converters for various types of
power supplies(engine control modules, HID lamps).

PRECAUTIONS
Care should be taken since product operation can become impaired under the following circumstances.
• The product should not be used after undergoing the mechanical stress of being dropped, etc.
• There are instances when performance can become impaired due to core cracking, etc., even though visual appearance of the product
is unaffected.
• Contamination, dust, fog, water droplets, and direct sunlight should be avoided during storage. Inappropriate storage conditions can
result in malfunctioning of the product.
• Operation and storage environments should be avoided that could cause corrosion(chlorine gas, oxygen gas, alkaline, etc.
environments).
• Excessive force should not be applied to the product by metal tools, etc. during mounting. Furthermore, the product should be kept
bare since encasing the product in resin, etc. can possibly result in degradation of the printed coil isolation characteristics and can
greatly alter inductance(lower L).
The product should be used under appropriate condition.
• TDK recommends applications utilizing the suggested board pattern. If the product is used under other conditions, the customer should
confirm that no problems result under manufacturing conditions.
• Required reflow conditions greatly depend upon board mounting conditions. Therefore reflow conditions must be confirmed by testing.
• In principle, cleaning should be avoided after mounting. If cleaning is carried out, cleaning conditions should be confirmed by reliability,
etc. testing.
Temperature rise, isolation, and abnormal conditions.
• The temperature rise of this product is greatly affecting by board mounting conditions. Therefore temperature rise must be confirmed
by testing.
• Caution should be used when carrying out insulation resistance testing above the rated voltage since the performance of insulation can
degrade under such conditions.
• Since this product does not have a built-in protective function to counter abnormal conditions such as excess load, short circuits, open
circuits, etc., testing must be carried out to confirm the absence of safety problems.
