Description
The C18A50Z4 is a high performance RoHS compliant Alumina (Al2O3) surface mount termination intended as a lower cost alternative to Aluminum Nitride (AIN) and Beryllium Oxide (BeO). The SMD termination is well suited to all cellular frequency bands such as: AMPS, GSM, DCS, PCS, PHS and UMTS. The high power handling makes the part ideal for terminating 90º hybrids, directional couplers, and for use in isolators. General Specifications Resistive Element Thick film Substrate Alumina Ceramic Terminal Finish Tin over Nickel Operating Temperature -55 to +125°C (see chart) Tolerance is ±0.010”, unless otherwise specified. Designed to meet of exceed applicable portions of MIL-E-5400. All dimensions in inches. Electrical Specifications Resistance Value: 50 ohms, ± 2% Power: 18 Watts Frequency Range: 1KHz – 2.3GHz Specification based on unit properly installed using suggested mounting instructions and a 50 ohm nominal impedance.
