IDC Low Inductance Capacitors (RoHS)
0306/0612/0508 IDC (InterDigitated Capacitors)
GENERAL DESCRIPTION
Inter-Digitated Capacitors (IDCs) are used for both semiconductor
package and board level decoupling. The equivalent series
inductance (ESL) of a single capacitor or an array of capacitors in
0612
parallel determines the response time of a Power Delivery Network
(PDN). The lower the ESL of a PDN, the faster the response time.
A designer can use many standard MLCCs in parallel to reduce
ESL or a low ESL Inter-Digitated Capacitor (IDC) device. These IDC
devices are available in versions with a maximum height of 0.95mm

or 0.55mm.

IDCs are typically used on packages of semiconductor products
with power levels of 15 watts or greater. Inter-Digitated Capacitors
are used on CPU, GPU, ASIC, and ASSP devices produced on
0.13μ, 90nm, 65nm, and 45nm processes. IDC devices are used
on both ceramic and organic package substrates. These low ESL
surface mount capacitors can be placed on the bottom side or the
top side of a package substrate. The low profile 0.55mm maximum
height IDCs can easily be used on the bottom side of BGA
packages or on the die side of packages under a heat spreader.

TYPICAL IMPEDANCE

IDCs are used for board level decoupling of systems with speeds of
300MHz or greater. Low ESL IDCs free up valuable board space by
reducing the number of capacitors required versus standard
MLCCs. There are additional benefits to reducing the number of
capacitors beyond saving board space including higher reliability
from a reduction in the number of components and lower
placement costs based on the need for fewer capacitors.

The Inter-Digitated Capacitor (IDC) technology was developed by
AVX. This is the second family of Low Inductance MLCC products
created by AVX. IDCs are a cost effective alternative to AVX’s first
generation low ESL family for high-reliability applications known as
LICA (Low Inductance Chip Array).
