HIGH CURRENT POWER CHOKES
RESISTORS CAPACITORS COILS DELAY LINES
HL SERIES
RoHS
Term.W is
RoHS
compliant
& 260°C
compatible
Low price, wide selection, 2.7µH to 100,000µH, up to 15.5A
Option ER Military Screening: per MIL-PRF-15305 Grp.A
Non-standard values & sizes, increased current & temp.,
inductance measured at high freq., cut & formed leads, etc.
HL chokes are specifically designed for high current applications.
The use of high saturation cores and flame retardant shrink
tubing makes them ideal for switching power supply circuits.
