All electronic components and assemblies are somewhat temperature sensitive. Precision circuits require temperature compensation to maintain precision over a range of temperatures. Certain analog circuits, microwave components, oscillators and microwave amplifiers need temperature compensation. Positive temperature coefficients thermistors PTC are used for active and passive temperature compensation. PTC thermistors are also used when absolute value of the ambient temperature needs to be known. In this case it is more practical and less expensive to calibrate the PTC against an absolute temperature reference. These devices can be used over the temperature range of -50°C to +200°C. Higher temperature ratings are available by special order. Devices are 100% tested, visual inspected and packaged in waffle packs, film frame or 6”/8” plastic or flat/metal rings. US Microwaves employs proprietary thin film technologies for deposition of a wide range of sheet resistance films from 1Ω/sq to 10,000Ω/sq. Resistors from 0.1Ω to 100,000Ω; range are available. The resistive material is high stability Platinum with positive temperature coefficient of resistance, 0.25% ±0.05% per °C typical.

PTC Thermistor (Pt RTD) DIE LAYOUT / MECHANICAL SPECIFICATIONS Silicon PTC PLATINUM Positive Temperature Coefficient Thermistors USMRPTC4550T10S-5% PTC Thermistor (Pt RTD) CHIP MOUNT Silicon PTC PLATINUM Positive Temperature Coefficient Thermistors USMRPTC4550T10S-5% thin film chip PTC thermistor mount PTC Thermistor (Pt RTD) ASSEMBLY PROCESS - SHORT APPLICATION NOTE Thin PTC thin film chip thermistors are designed for critical designs where space is at premium. The PTC thin film chip thermistors can be die attached to the PCB or to a base plate using AuSn or AuGe preforms. Since the PTC thin film chip thermistors do not have terminals, they have to be attached using gold wire after the backside is soldered in place. Backside metallization for thin film chip PTC thermistors is Ti/Pt/Au which is also compatible with Sn solder. For the more common SnPb, a Ti/Ni/Au backside metallization should be requested. Note: Actual resistor layout might vary due to laser trim requirements. STANDARD PRODUCTS ORDERING INFORMATION USM P/N WAFFLE PACK R [Ω] MIN.

 Silicon PTC PLATINUM Positive Temperature Coefficient Thermistors USMRPTC4550T10S-5%

PRODUCT DESCRIPTION AND SHORT APPLICATION NOTE
USMRPTC4550T10S-5% 10 mils Silicon (Si) series of thin film positive temperature coefficient thermistors are designed to be used in Inrush current limiters, Temperature sensors, Self-resetting over current protectors, Self-regulating heating elements, Precision, narrow band, temperature point matched control or Broader temperature range circuit compensation.
All electronic components and assemblies are somewhat temperature sensitive. Precision circuits require temperature compensation to maintain precision over a range of temperatures. Certain analog circuits, microwave components, oscillators and microwave amplifiers need temperature compensation. Positive temperature coefficients thermistors PTC are used for active and passive temperature compensation. PTC thermistors are also used when absolute value of the ambient temperature needs to be known. In this case it is more practical and less expensive to calibrate the PTC against an absolute temperature reference.
These devices can be used over the temperature range of -50°C to +200°C. Higher temperature ratings are available by special order.
Devices are 100% tested, visual inspected and packaged in waffle packs, film frame or 6”/8” plastic or flat/metal rings. US Microwaves employs proprietary thin film technologies for deposition of a wide range of sheet resistance films from 1Ω/sq to 10,000Ω/sq. Resistors from 0.1Ω to 100,000Ω; range are available. The resistive material is high stability Platinum with positive temperature coefficient of resistance, 0.25% ±0.05% per °C typical.

TECHNOLOGY DESCRIPTION: SEMICONDUCTOR-THIN FILM MANUFACTURING
All thin film microwave products are manufactured using advanced semiconductors and thin film technologies including ultra-stable and self passivating Tantalum Nitride resistors, gold interconnect metallization and reliable MNOS capacitors to achieve excellent uniformity, performance and reliability. Thin film technology is the preferred solution for all applications that require low noise, long term stability and excellent performance at very high frequencies. US Microwaves employs proprietary thin film technologies for deposition of a wide range of resistive films with sheet resistance films from 1Ω/sq to 10,000Ω/sq. All US Microwaves products are available in die form and are ideal for high reliability hybrid and multi chip module applications.
All US Microwaves products are manufactured using GOLD CHIP TECHNOLOGY™ a trade mark of Semiconix Corporation.

PTC Thermistor (Pt RTD) ASSEMBLY PROCESS - SHORT APPLICATION NOTE
Thin PTC thin film chip thermistors are designed for critical designs where space is at premium. The PTC thin film chip thermistors can be die attached to the PCB or to a base plate using AuSn or AuGe preforms. Since the PTC thin film chip thermistors do not have terminals, they have to be attached using gold wire after the backside is soldered in place. Backside metallization for thin film chip PTC thermistors is Ti/Pt/Au which is also compatible with Sn solder. For the more common SnPb, a Ti/Ni/Au backside metallization should be requested.

Note: Actual resistor layout might vary due to laser trim requirements.
