Resistor Networks, Arrays

Resistor networks and arrays come in different types, sizes, and shapes. The 4116R-2-220LF is one such type of resistor network and array. This specific type of resistor network and array is used in several applications, and its working principle is also interesting to explore.

About the 4116R-2-220LF

The 4116R-2-220LF is a resistor array module that combines two 220 Ω resistors in a single, 0.625” x 0.335” x 0.114” chip-based package. It is a resistor network with short lead length that has a wide operating temperature range of -55°C to +150°C. This type of resistor array provides higher circuit density compared to a discrete board mount resistors. It also reduces the number of parts, assembly time, and cost when mounting a variety of resistances in a circuit.

4116R-2-220LF Application Field

The 4116R-2-220LF is a common choice for many applications, including power and signal conditioning, computer peripherals, consumer electronics, and automotive equipment. It is used in applications that require a stable, low-resistance value over a wide temperature range; for example, it can be used as a current sensing and overload protection in motor control circuits, as a protection for input/output pins of an integrated circuit, or in signal sensitivity control. Its low thermal resistance is also beneficial in applications that require a low power dissipation.

Working Principle

The 4116R-2-220LF’s working principle relies on its two 220Ω resistors in series. When current flows through this network, a voltage drop occurs across the two resistors, and the two resistors share the current in proportion to their resistance values. As a result, the voltage at the end of each resistor is equivalent to 1/2 of the applied voltage, since each resistor contains 1/2 of the total resistance value. This voltage can then be used as a power source, or as a signal in some applications.

Benefits and Drawbacks

The 4116R-2-220LF has several advantages, including a small chip size, high operating temperature range, low thermal resistance, and low cost. Additionally, it offers high-precision tolerance and stability, allowing it to be used in precision applications. Its drawbacks include its low power handling capacity, low voltage range, and its susceptibility to inductive loads.

Conclusion

The 4116R-2-220LF is a resistor network and array with a wide range of applications. It features two built-in 220Ω resistors, a wide range of operating temperatures, and low thermal resistance. Its small chip size, high resistance tolerance, and low cost make it a popular choice for a variety of applications. However, its low power handling capacity, low voltage range, and susceptibility to inductive loads may make it unsuitable for certain applications.
