The 1530B103 is a 1000 uH (1 mH) sub-miniature RF choke with an iron core and a ±5% inductance tolerance, for engineers building network, filter and delay-line circuits.
It is the largest-value B-size part among the four listed here, with a 79 mA maximum DC current and 24 ohm maximum DC resistance, and it is characterised at a 0.79 MHz test frequency.
The 1530B103 specification: inductance 1000 uH (+/- 5%), Q minimum 30 at a 0.79 MHz test frequency, Fo minimum 1.4 MHz, maximum DC resistance 24 ohms and maximum DC current 79 mA. L and Q values are measured on a Q meter.
Physically it is a subminiature part: maximum coil diameter is 0.225 in on a 0.25 in (6 mm) form length (±0.03 in). The coil is varnish impregnated and wound on an iron core. Shipping weight is 0.1 lb (0.05 kg), and the part is RoHS and REACH compliant (UNSPSC 39121301, UPC 623980291307).
Note that the manufacturer states the 1530 Series will soon be discontinued as a stocked series and is available while quantities last, so plan ahead if you are specifying it for ongoing production.
