chip type voltage step-up coils
NEW
features
•
Small size and low profile. Designed to a compact
and thin shape requiring the least installation space,
suitable for small sized portable equipment.
•
High inductance. The unique wire-winding structure
achieves high inductance and low resistance and makes
this product suitable for high output performance and
high efficiency circuits.
•
Suitable for reflow soldering
•
Products with lead-free terminations meet
RoHS requirements
