HC-49US 13.56 MHz Quartz Crystal | 20pF | 20PPM | DIP Through-Hole

Description

The HC-49US 13.56 MHz Crystal is a high-precision quartz resonator, widely utilized as a standard reference frequency in RFID (Radio Frequency Identification) and NFC (Near Field Communication) applications. The 13.56 MHz frequency falls within the globally recognized ISM (Industrial, Scientific, and Medical) band, making it the primary choice for contactless card readers, smart tags, and short-range wireless data exchange systems.

Housed in the industry-standard HC-49US 2-pin through-hole package, this crystal provides superior mechanical robustness and is ideal for both prototyping and long-term production PCB designs. Its resistance-welded, hermetically sealed construction protects the delicate quartz element from environmental stressors like moisture and thermal fluctuations. With a tight frequency tolerance of 20 PPM and a standard load capacitance of 20 pF, it delivers the consistent, low-jitter clock signal necessary for stable wireless communication.

Key Features

• RFID/NFC Standard: 13.56 MHz is the foundational frequency for most contactless smart card and NFC reader systems.
