Create Free Business AccountThe 104K is a miniature interstage audio transformer in the 104 Series with a 20000 ohm primary and a 1000 ohm center-tapped secondary. It is aimed at P.C. board designs coupling a high-impedance stage into a lower-impedance, balanced load.
Rugged black epoxy potting gives a completely sealed unit that withstands severe environmental conditions, including those of MIL-T-27 (Grade 5, Class S). Its center-tapped secondary uses the series' bifilar winding technique for balanced resistive and capacitive characteristics. Mounting is by 0.025 in square pins (typical), 0.11 in +/-15% long, and connections that are not used have no pin.
Ratings for the 104K:
The 104K is RoHS and REACH compliant, ships at 0.05 lbs (0.02 kg), and carries UPC 623980180007. Its 20:1 impedance ratio sits between the 104H (10000 to 2000 ohms CT) and the 104L (25000 to 600 ohms CT) in the series.
