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

BACKSIDE METAL Platinum Pt The bonding pads of the resistors are 3µm thick, 99.99% electroplated gold with a TiW
barrier that withstands 30 min at 400°C in air without loss of adhesion. Backside metallization is Ti/Pt/Au. Other
metallizations are available upon special request. All US Microwaves products are available in die form. Typical
delivery for die products is 2-3 weeks ARO. For Custom designs, delivery is 3-4 weeks ARO. Certain items may be
available from stock. Inventory is periodically updated. All devices for chip and wire applications are 100% tested,
visual inspected and shipped in waffle packs (WP). PTC Thermistor (Pt RTD) DIE LAYOUT / MECHANICAL SPECIFICATIONS 150Ω

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
