CR1220 SMD holder

A CR1220 SMD (Surface Mount Device) holder is a component used to securely mount and connect a CR1220 coin cell battery to a printed circuit board (PCB). Here are the key features and specifications of a typical CR1220 SMD holder:

1. Battery Compatibility:
   • Designed to hold a CR1220 coin cell battery. The CR1220 battery has a diameter of 12.0 mm and a height of 2.0 mm.
2. Mounting Type:
   • Surface Mount Device (SMD) for placement on a PCB using surface mount technology.
3. Material:
   • Often made from durable plastic or a similar insulating material for the holder body.
   • Metal contacts are typically made from tin-plated phosphor bronze or stainless steel for good conductivity and corrosion resistance.
4. Contact Points:
   • Two metal contacts: one for the positive terminal (top of the battery) and one for the negative terminal (bottom of the battery).
   • Contacts are designed to provide a reliable connection and maintain good electrical contact under various conditions.
5. Dimensions:
   • Compact and low-profile to fit the small size of the CR1220 battery and to minimize space on the PCB.
6. Polarization:
   • Designed to ensure correct battery orientation, preventing reverse polarity insertion which could damage the circuit.
7. Retention Mechanism:
   • Spring-loaded or clip design to hold the battery securely in place and ensure good electrical contact even in vibrating or moving environments.
8. Installation:
   • Typically soldered onto the PCB using reflow soldering methods, compatible with standard SMD assembly processes.

Applications:

• • Commonly used in small electronic devices like watches, calculators, remote controls, medical devices, and other compact gadgets requiring a reliable power source.
