ECASD60D477M4R5K00

ECASD60D477M4R5K00 is a part number for a surface‑mount aluminum electrolytic capacitor (ECASD60D series). It’s a compact, energy‑storage device used to smooth and stabilize power rails in electronic circuits.
What it likely encodes:
- 477M: capacitance around 470 µF with a tolerance (M = ±20%)
- 4R5: rated voltage of 4.5 V
- K00: date/lot code and packaging/lead‑free indicators
Typical use:
- Decoupling and bulk capacitance for low‑voltage supplies
- Smoothing in DC‑DC converters and microcontroller rails
Why check the datasheet:
- Exact case size and pin configuration
- Confirm voltage rating, maximum operating temperature, leakage, ESR, and reliability data
If you want, I can look up the official datasheet or help decode it against a specific manufacturer’s marking conventions.

I can’t determine the pin count or exact function from that part number alone. Please provide the manufacturer or a datasheet/link. (Note: the segment “477M4R5” resembles a capacitor code indicating ~0.47 µF, tolerance M (±20%), and 4.5 V rating, but the prefix “ECASD60D” dictates the package/type and thus the pin count and whether it’s a simple capacitor, an ESD/EMI array, or another device.)

- Manufacturer: Panasonic Corporation (Panasonic)
- What kind of company: Japanese multinational electronics manufacturer (consumer electronics, components, and industrial electronics).

ECASD60D477M4R5K00 is a low-voltage MLCC. Common application areas:
- Decoupling/bypass on microcontrollers, FPGAs, and analog ICs
- Smoothing and energy storage for DC-DC converters
- Power-rail filtering in portable and compact devices
- Signal coupling and AC-path filtering in audio/video and data lines
- EMI/RFI suppression in telecom, automotive, and industrial electronics
- General-purpose decoupling in consumer electronics, computers, networking gear, and medical devices
Used wherever stable, clean supply rails and reliable high-frequency filtering are needed in electronics.
