USMRPTC4550T10S-103-1% 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. ELECTRICAL CHARACTERISTICS

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. QTY U/P [$]
