What are the key features of RHFL4913ESY331?

  • Radiation-hardened design rated for space-grade environments with TID tolerance
  • Fixed 3.3 V output with ultra-low dropout voltage of 0.95 V for power efficiency
  • Tight load and line regulation of ±0.0132% for stable supply rails in harsh conditions

What is RHFL4913ESY331 used for?

The RHFL4913ESY331 is designed for satellite power management systems and space-grade electronics where radiation hardness is critical. It provides a stable 3.3 V supply rail for FPGAs, microprocessors, and digital logic in LEO and GEO satellite platforms. Its fixed output and low dropout make it ideal for power-constrained space instruments and avionics subsystems.

Frequently Asked Questions

Which designs can use RHFL4913ESY331 when 3 pins is a required parameter?

RHFL4913ESY331 is a practical fit when the design needs 3 pins in a integrated circuit from STMicroelectronics. Buyers should confirm the package, lifecycle state, and original datasheet before approving it for production builds.

How should buyers compare RHFL4913ESY331 with alternate integrated circuit options?

Use 3.3 V as one verified requirement, then match the electrical ratings, footprint, and manufacturer series against the target BOM. This reduces substitution risk when similar parts differ in assembly or operating limits.

Which assembly detail should be checked before sourcing RHFL4913ESY331 for production?

Confirm that the selected lot matches TO-257 and the known 5.8 V requirement before RFQ approval. This gives incoming inspection and engineering teams a clearer basis for footprint, mating, or thermal review.
