Hammond 1530C823 8.2 mH Sub-Miniature Iron-Core RF Choke, 40 mA

The 1530C823 is a sub-miniature R.F. choke from the 1530 Series, rated at 8,200 uH (8.2 mH) with an iron core. It is intended for engineers and technicians building network, filter and delay-line circuits where a compact inductor with a specified Q and self-resonant frequency is needed.

The 1530C823 sits at 8,200 uH on an iron core with the 0.38 in form length, rated up to 40 mA DC with a maximum DC resistance of 92.4 ohms. Inductance tolerance is +/- 5%, with a minimum Q of 48 measured at a test frequency of 0.25 MHz, and a minimum self-resonant frequency (Fo) of 0.6 MHz. L and Q values for the series are measured on a Q meter.

Physically, the coil diameter is 0.33 in maximum and the form length is 0.38 in (10 mm), with a tolerance of +/- 0.03 in. Coils in this series are varnish impregnated, and the 1530 Series design ranges from only 0.25 in to 0.63 in in form length.

• Maximum DC resistance: 92.4 ohms
• Maximum DC current: 40 mA
• RoHS and REACH compliant; shipping weight 0.05 lbs (0.02 kg)

Please note that the manufacturer states the 1530 Series will soon be discontinued as a stocked series and is available while quantities last, which makes the 1530C823 a practical choice for maintaining or repairing existing designs that already specify it.
