Crystal Oscillator 2Pin HC-49S 4.897MHZ

Description

here are the typical specifications for an HC-49S crystal in the 4-5MHz range:

Parameter	Typical Value
Frequency Range4.897MHZ	(HC-49S package supports this)
Load Capacitance (CL)	20 pF (standard for 4.897MHz parts)
Frequency Tolerance	±50 ppm (at 25°C)
Frequency Stability	±50 ppm (over temperature)
Equivalent Series Resistance (ESR)	70Ω – 120Ω
Operating Temperature	-40°C to +85°C
Shunt Capacitance (C0)	7 pF Max
Drive Level	100 µW (standard)
Aging	±5 ppm/year

The HC-49S is a low-profile, resistance-welded metal can package:

Purpose: The 4.897MHz frequency is almost exclusively tied to PAL video color decoding/encoding and RF ASK applications , . If you’re repairing vintage video equipment or building a PAL video circuit, this is the correct crystal.
Load Capacitance Match: Ensure the circuit you’re using it in expects a 20pF load capacitance. Using a crystal with the wrong load capacitance will cause the oscillator to run off-frequency.
