概述

Description

SRP1770TA-470M is likely an SMT power inductor from the SRP series (used in DC–DC converters and filtering). The marking “470M” typically means about 47 µH inductance with M tolerance (±20%). The “TA” and “1770” are the manufacturer’s series/temperature/size codes and footprint, which vary by maker.
What to verify in the datasheet:
- Nominal inductance value (about 47 µH) and tolerance
- Rated current (I_R) and saturation current
- DC resistance (DCR)
- Temperature range and terminations/footprint
- Package size and mounting recommendations
Typical application: energy storage in switch-mode regulators, input/output filtering, and ripple suppression.
For an exact introduction, please share the manufacturer or a datasheet link, and I’ll summarize the precise specs, footprint, and recommended usage.

Features

- Type: Shielded surface-mount power inductor (SRP series)
- Inductance: 47 µH (code 470)
- Tolerance: ±20% (M)
- Core: Ferrite, epoxy-molded for durability
- Packaging: SMD with robust terminations (tape/reel options often available)
- Electricals: Low DC resistance; high saturation current suitable for switching regulators
- Applications: Ideal for DC-DC converters and other SMPS circuits
- Environment: RoHS compliant; wide operating temp range (typical -40°C to +125°C)
Note: For exact current rating, DCR, and dimensions, refer to the specific datasheet.

Package

SMT (surface-mount) power inductor in a 1770-size package (approx. 17.0 × 7.0 mm).

Pinout

Pin count: 4.
Function: Four-terminal Kelvin shunt resistor (low-value sense resistor) for high-current measurement. Two outer pins carry the current (I+ and I−); two inner pins provide the sense voltage (V+ and V−) across the 0.470 Ω value.

Application

SRP1770TA-470M is a power-electronics component. Typical application areas include:
- DC-link decoupling and energy storage in switching power supplies and DC-DC converters
- Input/output filtering for motor drives and inverters
- Automotive and industrial electronics
- Power filtering in telecom equipment and general high-current decoupling in consumer electronics
Note: refer to the manufacturer’s datasheet for exact usage, ratings, and installation guidelines.
