# 109RF50-1-A-5/2D (Component) ## Description The 109RF50-1-A-5/2D is a Pickering Electronics Series 109 Micro-SIL® RF reed relay designed for high-density PCB applications requiring low-level signal switching and excellent RF performance. It features a 50 Ω coaxial configuration, SPST normally open (1 Form A) contact arrangement, and a 5 VDC coil with an integrated diode for coil suppression. The relay uses a mu-metal magnetic shield package to minimize magnetic interaction when multiple relays are closely stacked, making it suitable for compact test systems, RF switching matrices, and high-speed signal applications. Key Features Relay Type: Micro-SIL® RF Reed Relay Manufacturer: Pickering Electronics Series: Series 109 Contact Configuration: SPST-NO (1 Form A) Coil Voltage: 5 VDC Coil Resistance: 375 Ω Switching Current: Up to 0.5 A Switching Power: 10 W Maximum Switching Voltage: 200 V Standoff Voltage: 240 V Contact Type: Low-level dry reed contact RF Characteristic Impedance: 50 Ω coaxial configuration Integrated Protection: Internal diode included Package Type: Through-hole Micro-SIL (SIP) Magnetic Shielding: Mu-metal package for reduced relay interaction in dense layouts Operating Temperature: Approximately -20 °C to +85 °C High Density Mounting: Stackable on 0.15 × 0.6 inch pitch for space-saving PCB designs Typical Applications RF signal switching systems Automatic Test Equipment (ATE) switching matrices High-speed digital signal switching RF filters and instrumentation equipment Communication test platforms Precision measurement equipment #PickeringElectronics #109RF50 #ReedRelay #RFRelay #MicroSILRelay #SPSTRelay #SignalSwitching #RFSignal #ATEEquipment #TestAndMeasurement #PCBRelay #HighDensityDesign #ElectronicComponents ## Component Details - **Owner:** adrian95 - **Created:** 6/19/2026 - **Last Updated:** 6/19/2026 - **Visibility:** Public - **Part Type:** Reed Relays - **Manufacturer Part Number:** 109RF50-1-A-5/2D - **Symbol Style:** parametric-v1 - **Datasheet URL:** https://www.pickeringrelay.com/pdfs/109-micro-sil-reed-relays.pdf - **Manufacturer Name:** Pickering Electronics - **License:** https://creativecommons.org/licenses/by/4.0/ - **Part Type:** Electromechanical Components - **MPN:** 109RF50-1-A-5/2D - **Mount Type:** Through Hole - **Package / Case Code:** TO - **Pin Count:** 6 ## Pins | Pin | Name | Type | |-----|------|------| | 1 | RF CONTACT A | | | 2 | RF SHIELD A | | | 3 | COIL+ | | | 4 | COIL− | | | 5 | RF SHIELD B | | | 6 | RF CONTACT B | | --- *Generated from [https://www.flux.ai/adrian95/109rf50-1-a-52d~kjp](https://www.flux.ai/adrian95/109rf50-1-a-52d~kjp)*
