224-955-1644Key Features
- 2.5 mH inductance, +/- 10% tolerance
- Rated 125 mA D.C. current
- 44 ohm D.C. resistance
- 4-pie winding on a low loss ceramic form
- 1.50 in (38 mm) length; 0.5 oz.
- RoHS and REACH compliant
- Series available while quantities last
The 1504 is a 2.5 mH R.F. choke from the 1500-1521 Series for keeping radio-frequency energy out of D.C. supply and bias paths. It has an inductance of 2.5 mH with +/- 10% tolerance, a D.C. current rating of 125 mA and a D.C. resistance of 44 ohms.
The winding is divided into 4 pies on a ceramic form; the series describes its forms as low loss ceramic or powdered iron. The 1504 measures 1.50 in (38 mm) long and weighs 0.5 oz. per the series table. Compared with the 1501 it trades inductance (2.5 mH versus 10 mH) for a higher 125 mA current rating.
It is a fit for RF engineers, radio amateurs and OEM designers who need a moderate-current RF choke in plate, collector or bias feeds. The 1504 is RoHS and REACH compliant, ships at 0.1 lbs (0.05 kg), and carries UPC 623980290003 and UNSPSC 39121301.
Hammond notes that the 1500-1521 R.F. choke line will soon be discontinued as a stocked series and is available while quantities last; for alternative solution assistance Hammond lists USA (716) 630-7030 and Canada and International (519) 822-2960.
Ideal For
- RF plate or collector feed chokes
- RF bias decoupling
- Amateur radio equipment
