The TCD-10-4-75X+ is a surface mount directional coupler designed for 75Ω CATV systems operating from 5 to 1000 MHz with a nominal coupling of 9.9 dB. It features a top hat package with dimensions of 3.81 × 3.81 × 0.33 mm and weighs 0.15 grams. The device maintains a mainline loss of 1.5 dB maximum across the band, a coupling flatness of ±0.3 dB, and a directivity greater than 11 dB up to 1000 MHz. Input power is rated at 1.0 W, with a VSWR of 1.25:1 maximum. Operating temperature ranges from -40°C to +85°C, and it is aqueous washable. The pin configuration and land pattern are compatible with the EMDC-10-1-75.
