Application Guidelines
1. Typical Application Circuit
- Recommended IC: TC74HCU04 (TOSHIBA)
- Supply Voltage (Vcc): 5 V
- External Components: Rf = 1 MΩ, Rd = 680 Ω (per MYC7 type test circuit)
- Note: Built-in loading capacitors (7.0 pF each) eliminate need for external CL components
2. Key Design Notes
- Ensure PCB land pattern matches MYC7 type dimensions (2.0×1.6 mm) for proper soldering
- Avoid excessive mechanical stress (bending, dropping) to prevent frequency drift or damage
- Operate within specified temperature range to maintain frequency stability
- Store in dry environment (avoid humidity >95% RH) when not in use
3. Reliability Test Compliance
- Low/high temperature storage (1000h each at –40±3°C and +85±2°C)
- Loading humidity resistance (1000h at 60±2°C, 90–95% RH)
- Soldering heat resistance (peak 260°C, 10s)
- No significant frequency change (±0.25% max), resonant resistance change (±10 Ω max), or appearance abnormalities after tests
