What are the key features of RI-1212S?

12 V nominal input range (10.8 V to 13.2 V) for direct connection to standard 12 V power rails
4-pin SIP (SMA) package enabling vertical through-hole mounting in tight board layouts
Up to 10% load regulation for unregulated isolated DC-DC power conversion in non-precision applications
RoHS and REACH compliant Pb-free construction for global regulatory and environmental compliance

What is RI-1212S used for?

The RI-1212S is designed for isolated DC-DC power conversion in industrial automation, instrumentation, and telecom equipment that require a compact 4-pin SIP module powered from a 12 V bus. Its unregulated single-output topology is appropriate for powering analog signal conditioning stages, relay drivers, and isolated communication interfaces where ±10% output variation is acceptable. The small SMA through-hole footprint simplifies integration into existing board layouts without redesigning power plane structures.

Frequently Asked Questions

What input voltage range does the RI-1212S support, and how does it affect use with a 12 V battery system?

The RI-1212S accepts an input voltage from 10.8 V minimum to 13.2 V maximum, centered on a 12 V nominal supply. This 10% tolerance on each side covers typical 12 V lead-acid battery voltage during both float charge at 13.2 V and partial discharge down to 10.8 V, making the RI-1212S directly usable in 12 V UPS and battery backup systems without additional pre-regulation.

How does the 10% maximum load regulation of the RI-1212S limit its use in precision analog circuits?

With up to 10% load regulation, the RI-1212S output voltage shifts by up to 10% as load current changes from no-load to full-load. For a 12 V output this represents a ±1.2 V swing, which is unacceptable for precision ADC reference rails requiring ±0.1% or better regulation. The RI-1212S is therefore best suited for relay drivers, optocoupler power supplies, and isolated gate driver rails where output variation within 10% does not degrade system performance.

For a 4-pin SIP form factor, how does the RI-1212S physically fit into standard PCB layouts compared to DIP-8 converter modules?

The RI-1212S SMA (R-XSMA-P4) package uses a 4-pin single in-line arrangement with a footprint approximately 7.5 mm wide and 19 mm long, roughly half the board area of a DIP-8 converter module at 10 mm x 24 mm. This 40-50% reduction in footprint makes it practical for single-supply isolated converter placements in instrument amplifier boards and industrial I/O modules with less than 2 cm² allocated to the power section.
