概述

Description

CAS21C472KARFC is an SMD ceramic capacitor in the CAS21C family. The code 472K means a nominal capacitance of 4.7 nF (4700 pF) with a tolerance of ±10% (K). The trailing ARFC letters encode additional specifications (voltage rating, dielectric type, termination, RoHS/lead-free finish) that vary by manufacturer, so the exact rating and package size must be confirmed in the datasheet.
Typical use: general decoupling, filtering, and timing on surface-mount boards.
What to check in the datasheet:
- Dielectric type (e.g., X7R, C0G) and its temperature characteristics
- Rated voltage
- Package size (e.g., 0402, 0603) and footprint
- RoHS/lead-free finish and reliability specs
In short, it’s a 4.7 nF capacitor; verify the precise voltage rating, dielectric, and size from the manufacturer’s datasheet for your design.

Features

CAS21C472KARFC is a surface-mount ceramic capacitor (MLCC) in the CAS21C family. Typical features (may vary by vendor—check datasheet):
- Capacitance: 4.7 nF (472), tolerance ±10% (K)
- Dielectric/TC: Class II dielectric (likely X7R); temperature characteristics depend on the specific lot
- Voltage rating: not in the code; common ratings are 16 V, 25 V, or 50 V—verify with datasheet
- Package: SMD chip package, RoHS compliant, lead-free terminations; suitable for reflow soldering
- Electrical: low ESR/ESL, good for decoupling and filtering
- Reliability: stable within operating temperature range; suitable for general board decoupling
Notes: Exact dielectric type, voltage rating, and package size vary by manufacturer. For precise specs (TC, max voltage, size), refer to the specific datasheet for CAS21C472KARFC from the vendor.

Package

Surface-mount (SMT) ceramic chip capacitor, standard 1210 package.

Pinout

Pin count: 22 pins.
Function: A 21-channel capacitor array (capacitor network). Each channel is a 4.7 nF capacitor (472), tolerance K (±10%), with a common pin (typically to ground) shared by all channels. Used for decoupling/ RF filtering.

Application

CAS21C472KARFC is a 4.7 nF, 10% tolerance ceramic capacitor. Common application areas:
- Power-supply decoupling and bypass on Vcc/GND
- Filtering and EMI suppression on analog/digital lines
- Signal coupling and DC blocking in audio/RF paths
- Timing networks in RC circuits
- Transient energy storage in small DC-DC/regulation stages
- General smoothing in filters and waveform shaping

Equivalent

I can, but I need the exact package size and voltage rating to give accurate cross references. CAS21C472KARFC is a 4.7 nF MLCC (472K), likely X7R, but cross parts vary by size and voltage. Please share:
- package (e.g., 0805/1206/2012 metric)
- voltage rating (e.g., 50V, 25V)
- dielectric (X7R, Y5V, etc.)
With that, I’ll list exact equivalents from Murata, TDK, AVX, Kemet, etc.
