| 2 | +# CR1220-dat |
|
| 3 | + |
|
| 4 | +The CR1220 is a lithium coin cell battery with the following key features: |
|
| 5 | + |
|
| 6 | +Specifications: |
|
| 7 | +- Diameter: 12 mm |
|
| 8 | +- Thickness: 2.0 mm |
|
| 9 | +- Nominal Voltage: 3V |
|
| 10 | +- Capacity: Approximately 35-40 mAh (varies by brand) |
|
| 11 | +- Chemistry: Lithium Manganese Dioxide (LiMnO2) |
|
| 12 | +- Operating Temperature Range: -30°C to +60°C |
|
| 13 | + |
|
| 14 | +Common Applications: |
|
| 15 | +- Watches |
|
| 16 | +- Calculators |
|
| 17 | +- Car key fobs |
|
| 18 | +- Small medical devices (like glucose meters) |
|
| 19 | +- Motherboards (for CMOS memory) |
|
| 20 | +- Small toys |
|
| 21 | + |
|
| 22 | +Advantages: |
|
| 23 | +- Long Shelf Life: Typically 5-10 years due to low self-discharge rates. |
|
| 24 | +- High Energy Density: Ideal for compact devices. |
|
| 25 | +- Stable Voltage Output: Ensures consistent device operation. |
|
| 26 | + |
|
| 27 | + |
|
| 28 | +## Pulse Current |
|
| 29 | + |
|
| 30 | +The CR1220 lithium coin cell battery is designed for low-power devices, and its discharge current specifications depend on the manufacturer and application. Here's an overview: |
|
| 31 | + |
|
| 32 | +1. Continuous Discharge Current |
|
| 33 | +- Typical Range: 0.1 mA to 0.2 mA |
|
| 34 | +- This current is sufficient for steady operation in devices like watches, calculators, and small sensors. |
|
| 35 | + |
|
| 36 | +1. Maximum Pulse Discharge Current |
|
| 37 | +- Typical Range: 1 mA to 5 mA (varies by brand) |
|
| 38 | +- The battery can briefly supply higher currents for short bursts, such as transmitting signals in key fobs or powering small LEDs. |
|
| 39 | + |
|
| 40 | +### Important Notes: |
|
| 41 | + |
|
| 42 | +Overloading the Battery: |
|
| 43 | + |
|
| 44 | +If the discharge current exceeds the specified range for a long time, it may cause: |
|
| 45 | +- Sudden voltage drop |
|
| 46 | +- Reduced capacity |
|
| 47 | +- Battery heating or leakage |
|
| 48 | + |
|
| 49 | +Brand Variation: |
|
| 50 | + |
|
| 51 | +Manufacturers like Panasonic, Sony, or Maxell may have slightly different specifications for their CR1220 batteries. Always check the datasheet for the specific brand you're using. |
|
| 52 | + |
|
| 53 | +### Recommendations: |
|
| 54 | + |
|
| 55 | +If your device requires higher discharge currents (e.g., above 10 mA), consider: |
|
| 56 | + |
|
| 57 | +Adding a Capacitor: To handle short bursts of high current. |
|
| 58 | +Using a Larger Battery: Such as CR2032 or CR2450, which are better suited for higher-power applications. |
