112-1-A overview
112-1-A is a component documented by Copyright Pickering Ele. The PDF description identifies it as "Single-in-Line SIL/SIP Reed Relays ISSUE 1.4 MAY 2024." This guide condenses the most useful engineering information from the available PDF so that designers and sourcing teams can identify the checks that still need confirmation in the original document.

Specifications and operating details
The following points were extracted from the PDF text. Check the associated conditions, notes and limits in the complete document before using a value in a design.
- The 5 V coil version has a resistance of 500 Ω and may be driven directly from TTL logic.
- The Series 112 is encapsulated in a plastic package using a very high resistivity resin to achieve an insulation resistance greater than 1012 Ω.
- For example, for an ‘end of life’ contact resistance specification of 1 Ω, switching low loads (10 V at 10 mA resistive) or when ‘cold’ switching, typical life is approx 1 x 109 ops.
- Operating Temperature Range -20 ºC to +85 ºC Storage Temperature Range -35 ºC to +100 ºC Shock Resistance 50 g Vibration Resistance (10 - 2000 Hz) 20 g Soldering Temperature (max) (10 s max) 270 ºC Washability (Proper drying process is rec.
- This means that at 125 °C the coil drive voltage will need to be increased by approximately 40 x 0.4 =16% to maintain the required magnetic drive level.
- Operating Voltages Coil voltage - nominal Must operate voltage - maximum at 25 °C Must release voltage - minimum at 25 °C 3 V 2.25 V 0.3 V 5 V 3.75 V 0.5 V 12 V 9 V 1.2 V cold switching techniques are often used.

Engineering review checklist
- Confirm repetitive reverse voltage, average forward current, surge current and leakage at the intended temperature.
- Check forward-voltage loss and reverse-recovery behavior at the actual current and switching frequency.
- Review package thermal resistance, copper area, polarity marking and transient derating before layout release.
Always confirm values against the latest manufacturer-controlled datasheet, especially when qualifying a substitute or releasing a production BOM.
