CM7V-T1A 0.3

Product catalog summary

Product Overview: The CM7V-T1A 0.3 is a low-frequency SMT Quartz Crystal Unit featuring a tuning fork Quartz Crystal Resonator. It is housed in a hermetically sealed ceramic package with a metal lid, designed for applications in IoT, industrial, healthcare, smart cards, ultra-thin devices, wearables, and portables.

Specifications: The crystal operates at a standard frequency of 32.768 kHz with load capacitance options of 6.0, 7.0, 9.0, and 12.5 pF. It offers frequency tolerances of ±20 ppm and ±100 ppm, with tighter tolerances available upon request. The series resistance is typically 45 kΩ, with a maximum of 60 kΩ. Motional capacitance is 3.6 fF, and static capacitance is 1.4 pF. The maximum drive level is 0.5 μW, and insulation resistance is at least 500 MΩ. Aging in the first year is limited to ±3 ppm.

Environmental Characteristics: The crystal can operate within a temperature range of -40 to +85°C, with extended ranges available. It is resistant to shock (5000 g, 0.3 ms, ½ sine) and vibration (20 g / 10–2000 Hz), both with a deviation of ±5 ppm.

Features: The CM7V-T1A 0.3 boasts an ultra-low profile with a maximum height of 0.35 mm, excellent hermetic sealing, high stability, low aging, and resistance to shock and vibration. It is 100% Pb-free and RoHS-compliant.

Packaging and Processing: The unit is designed for SMT mounting with Au flashed pads and follows IPC/JEDEC J-STD-020C processing standards, with a maximum temperature of 260°C for 20-40 seconds.

Ordering Information: Specifications are subject to change, and unique part numbers are generated for each product specification. Standard packaging includes 1,000 pcs or 3,000 pcs in 12 mm tape on a 7" reel.
