These are low-cost, high Q, radial lead inductors. This unique configuration mak them ideally suited for use in high density
es
printed circuit board assemblies. The flat coil configuration also offers twice the inductance and Q v
alues as axial lead
inductors. Epoxy coating and shrink tubing are available by special order.
INDUCTANCES 1.0µH to 10.000µH
CURRENT RATING Based on current flow and temperature rise
of 20°C maxim
um at 80°C ambient temperature.
OPERATING TEMPERATURE - 20°C to +100°C.
INDUCTANCE TOLERANCE ±10% over entire range
TERMINAL STRENGTH 5 lb. minimum
TESTING Inductance and Q measured on Q meter HP4342A
at specified frequency. SRF measured on Grid Dip Meter or
equivalent. DCR measured on Digital Milliohm meter
.
MARKING Inductance value (i.e. 1R0K)
