RL1220S-R10-F Resistors

Chip Resistor - Surface Mount

The RL1220S-R10-F Chip Resistor is a type of surface mount resistor, meaning it is designed to be soldered directly to the surface of a printed circuit board (PCB). This type of resistor is typically used in applications requiring high accuracy and very small power handling capabilities. It offers various advantages over through-hole resistors, including saving space on the board and allowing for faster assembly and better performance.

The RL1220S-R10-F is a very small surface mount resistor, measuring in at 1.2 mm by 2.0 mm, making it ideal for tight spaces and applications with limited circuit board real estate. The resistor is made from a nickel-chromium metal alloy with an operating temperature range of -55°C to +170°C. The resistor is rated for a power rating of 0.125 W (125 mW) and has a tolerance range of +50/-25%. The rated resistance of the device is 10 Ohms and it includes a flame-retardant UL 94-5VA approved coating.

The RL1220S-R10-F is typically used in applications such as automotive, computers, consumer electronics, industrial automation and military that require a high degree of accuracy in the power output, as well as a very small form factor. It is suitable for applications involving power supplies, processors, LED lighting, power converters, and motor control. The small size of the device means it can be used in incredibly tight spaces with difficult access, such as on the back of a printed circuit board.

The working principle of the RL1220S-R10-F is quite simple. It is basically a resistor element with two leads which connect to the circuit board and an internal connection between the leads. When a current is passed through the leads, a voltage is generated across the internal connection, which is directly proportional to the current. This voltage can then be used to calculate the resistance of the device, which is then used to control the current being passed through the circuit.

The RL1220S-R10-F is a very reliable and versatile surface mount resistor and is ideal for applications which require high accuracy and a very small form factor. It is durable enough to withstand tough environments and temperatures and can be used in a broad range of applications. Its small size means that it can be used in applications with limited circuit board space, making it a great choice for designs with a lot of components.
