Product details

This bulk RG142B/U cable can be used in applications where cable assemblies must be built in the field. The FEP outer jacket helps this cable achieve a 200 degree C operating temperature. And the 18 AWG solid center conductor results in a cable with low insertion loss characteristics. Spool may contain more than one piece.

Description

Current reference data for RG142B-1K: 50 Ohm · 8 GHz. Impedance is listed as 50 Ohm. If that parameter is critical, confirm it again in RFQ. Frequency is listed as 8 GHz. The real operating limit still depends on the assembly, mating pair, and application context. For higher-frequency projects, include the drawing, cable path, and critical requirements in the first RFQ. If mounting is missing here, confirm it from the drawing or mating requirement. Material is listed as FEP. That is useful for review, but it does not replace full project stack-up confirmation. Use this page to shortlist before RFQ, not as the final sign-off.

Use this page to shortlist before RFQ. MOQ 200+ custom production and supply path are confirmed after drawing/spec/BOM review; no spot stock is assumed.
