Product details

CA-400UF-R1K — L-com's CA-400UF Ultra Flex coax cable is deal for indoor or outdoor applications that require maximum flexibility due to curves, bends and twists. In addition these cables have excellent low loss characteristics. The CA-400UF low loss cable is a high performance alternative to Times Microwave LMR®-400UF and TerraWave® TWS-400UF. See data sheet and drawing for additional information and complete specifications.

China-sourced compatible alternative — fit confirmed by drawing/spec review.

Description

Current reference data for CA-400UF-R1K: 50 Ohm · 4.94 dB · 0.405 in. Impedance is listed as 50 Ohm. If that parameter is critical, confirm it again in RFQ. Frequency is listed as 4.94 dB. The real operating limit still depends on the assembly, mating pair, and application context. If mounting is missing here, confirm it from the drawing or mating requirement. Material is listed as TPE. 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.
