SRP1038A-2R2M

I’m not finding a widely published datasheet for SRP1038A-2R2M. It’s likely a part from a specific supplier, and the -2R2M suffix could indicate a version, value, or tolerance used by that vendor. Without the manufacturer or datasheet, I can’t give a precise introduction.
If you share the manufacturer or a link to the datasheet, I’ll summarize quickly. In general, an intro would cover:
- What the part is (e.g., regulator, sensor, transistor, resistor network)
- Key electrical specs (supply/operating voltage, current, temperature range)
- Package and pinout
- Typical applications
- Notable features (protection, accuracy, enable pins)
If you can’t provide the datasheet, I can guide you on how to read it: look at the overview, electrical characteristics, absolute maximum ratings, recommended operating conditions, and the typical application circuit.

I’m not sure of the exact part without the datasheet. SRP1038A-2R2M likely is a current-sense/shunt resistor, but cross-references depend on power rating, tolerance, and package. Please provide or confirm:
- power rating (W)
- package (e.g., 2512, 1206)
- tolerance
Or share the datasheet, then I’ll give precise equivalents from Vishay, Yageo, Bourns, etc.

SRP1038A-2R2M is a shielded surface‑mount power inductor. Key features:
- Inductance: 2.2 µH (2R2) with ±20% tolerance (M)
- Package: 10 × 8 mm (1038 size), SMT, shielded ferrite core
- DC resistance: very low for high efficiency
- Saturation/current: high saturation current suitable for DC-DC converter use
- Temperature range: -40 °C to +125 °C
- Construction: shielded to reduce EMI; robust mechanical performance
- RoHS/compliant: lead-free and reflow solderable
- Applications: DC-DC converters, power rails, voltage regulation circuitry
Note: exact I_sat and DCR values vary; consult the datasheet for precise electrical specs.

Pin count: 6 pins (SOT-23-6/TSOT-23-6).
Function: A step-down (buck) DC-DC switching regulator with enable and feedback control (VIN, GND, EN, FB, SW/LX, plus an exposed pad/NC as applicable). External inductor and diode (or a synchronous switch) are required. Exact pinout varies by package—consult the datasheet for the precise mapping.

- Manufacturer: Susumu Co., Ltd.
- What kind of company: A Japanese electronics components manufacturer, specializing in precision resistors, shunt/current-sense resistors, and other passive components.
