WW12FT140R application field and working principleThrough Hole Resistors act as an electronic component which features a resistance in the electrical circuit allowing an operator to control the current flow. The resistance level is dependent on the material used to produce the resistor and is designated with ohms in electrical terms. The most common methods of providing resistance are through wire wound, composition, and carbon. Among them, WW12FT140R is a kind of high performance Through Hole Resistor.The WW12FT140R is typically a 12-ohm Through Hole Resistor with a tolerance of 5%. It designed for use in high frequency and high performance circuit applications, and is manufactured with a wide range of high temperature and high frequency materials so it can be used in a variety of applications. The nominal value of the resistor can range from 0.1Ω to 1MΩ and each resistor is quite stable over a wide temperature range. It also has a wide operating temperature range from –55°C to +200°C and can be used in both open and closed resistors.The WW12FT140R is a metal oxide resistor which helps to reduce the contact resistance and improve the reliability of the resistor. It is composed of a resistive layer formed by the method of electron beam vapor deposition. It is used in temperature-sensitive bias circuits which require high stability and low voltage build-up. Additionally, the resistor is very small in size, so it can be used in very tight places.The WW12FT140R uses a resistive wire which is then engineered into a straight line configuration and encased in the resistor body. This allows the resistor to use the entire surface area for controlled current flow and prevents any contact failure or movement of the resistive material due to shock or vibration. Additionally, the resistive material has a higher temperature coefficient than other forms of resistor which helps to reduce medium and long term drift in the resistor under temperature conditions without affecting its stability.The WW12FT140R offers a range of applications, from RF and microwave networks for low-level signaling to DC and AC power supplies for power supply and control applications. It can also be used in high performance amplifiers and telecommunication systems. The operating voltage for the resistor ranges from 5V up to 100Vdc and can safely carry up to 10A without heating up due to the low thermal resistance and efficient cooling system built into the resistor.In summary, the WW12FT140R is a high performance Through Hole Resistor specifically designed to meet the needs of a wide range of industries and applications. Its wide operating temperature range and high current bearing capabilities make it ideal for use in high temperature and high frequency circuits, while its small size makes it ideal for tight places. The resistor also has a higher temperature coefficient which helps to reduce medium and long term drift under temperature conditions while still maintaining stability and reliability.
