DESCRIPTION AND SHORT APPLICATION NOTE USMC5500-25V Series of MIS chip capacitors are designed to be used in chip and
wire hybrid circuits as RF bypass, DC blocks coupling filter elements and microwave circuit resonant elements. When
used as resonant elements in oscillators, Q has to be as high as possible while the temperature coefficient has to be
as small as possible. US MICROWAVES advanced semiconductor and thin film technologies allow for an important reduction
of series resistance DCR, increased SRF, low insertion loss and skin effect at higher microwave frequencies. High
quality dielectrics with low loss factors translate into an increased Q, very high insulation resistance, high
breakdown voltage, long term stability under bias at high temperatures. US Microwaves MIS chip capacitors exhibit Q
values in excess of 3000 in X band, insertion loss less than 0.08dB through Ku band and series resistance much lower
than conventional ceramic chip capacitors. DCR of less than 0.1 ohms is typical for most chip sizes. MIS capacitors
with silicon nitride/silicon oxide dielectric, also known as MNOS capacitors exhibit high stability, low temperature
coefficients, low leakage in ≤nA range and high BV from 5, 10, 25, 50, 100 to 300V. MIS Chip capacitors are available
in a wide range of die sizes, capacitance values and breakdown voltages. 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 @25°C PARAMETER VALUE

maximum withstanding voltage WV. Long term reliability will be adversely affected and severe damage of devices may
result. Note 2: This information is provided to users to be aware of this device ESD sensitivity and take appropriate
measures to prevent permanent damage. Please see NOTE 1. ESD warning! MIS capacitors are ESD sensitive. ONLY Proper die
handling equipment and procedures should be employed. Stresses beyond listed absolute maximum ratings may cause
permanent damage to the device. GENERAL DIE INFORMATION SUBSTRATE THICKNESS [mils] DIE SIZE LxW [mils] Silicon (Si) 5±1

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

MOS) Chip Capacitors are designed for critical designs where space is at premium. The Silicon Microwave MIS (MNOS, MOS)
Chip Capacitors can be die attached to the PCB or to a base plate using AuSn or AuGe preforms. Since the Silicon
Microwave MIS (MNOS, MOS) Chip Capacitors do not have terminals, they have to be attached using gold wire after the
backside is soldered in place. Backside metallization for Silicon Microwave MIS (MNOS, MOS) Chip Capacitors 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. STANDARD PRODUCTS ORDERING INFORMATION USM P/N C [pF] WAFFLE PACK MIN. QTY U/P [$] FILM FRAME MIN. QTY U/P
