Supercapacitors vs. Tantalum capacitors
for pulse applications
12
Introduction
 The market for wireless applications is growing at a phenomenal
rate, using GSM/GPRS, Bluetooth, ISM, Zegbee or WiFi transmission.
 Many battery operated appliances need to have high capacitance
(high CV) capacitors, with low ESR and low leakage current to
manage the pulse requirements.
 High CV tantalums are being developed and launched during last few
years by leading Ta capacitors manufacturers presenting
capacitances of 2.2 and 3.3 mF.
oThus, for more demanding applications, banks of tantalum capacitors are used
in order to satisfy the demands.
oWhereas the capacitance of the smallest SC of Cellergy (12x12 mm) is of about
10 mF.
 Going to higher CV for tantalum capacitors meets with growing
challenges and limitations in process and materials.

Introduction to SSD applications
 SSDs need power fail data protection.
 Many SSD manufacturers use supercapacitors (SCs) for that
purpose while others prefer using Tantalums.
 When high capacitance is required the only reasonable
solution is using SCs to avoid data loss in the event of power
failure.

Intel SSD Application – case study conclusions
 Intel explained that they use 6 Tantalums instead of a SC since it is a less expensive
solution “getting the same intended job done”
 From comparison done lastly, using 6 tantalums vs. one SC is a more expensive
solution
 Since Tantalum is a rare material price is expected to continue growing and availability
to decrease.
 For large capacitance requirements need to use large number of Tantalums (bank
array), with increasing reliability issues, compared to one or two SCs for same
application.

Smart Metering Application
Background
A Smart Meter is a digital device that records the amount of
electricity, water or gas we use and transmits this information via
RF communication (GSM or ISM) to the utility provider.
The Challenge
Batteries that power Smart Meters are limited to low currents
and in most cases can't drive high current pulses for wireless
communication
Solution
Thanks to their low ESR and high power density Supercapacitors
or Tantalums, implemented in parallel to batteries, able to
deliver high current pulses

Pulse Requirement for GSM Transmission





Pulse peak – 2A
Pulse width - 577µs
Battery voltage – 3.6V
Operating voltage – 3V
Maximum voltage drop – 0.6V
The Challenge: Battery unable to drive required pulse
The Solution: SC or Tantalum connected in parallel to the
battery deliver the pulse
Conclusion:
It forces HW designer to use capacitors with
at least 6mF capacitance.
29
Smart Metering Application – GSM band solution
Background:
GSM transmissions are composed of short power bursts with a high current 2A.
Battery voltage is 3.6V. GSM transmitter operates at working voltage of 3V when the maximum
current pulse is 2-3A. The regular battery is unable to drive current of 2A due to its high internal resistance.
The solution is to connect SC or tantalum capacitor in parallel to the battery. Due to their low ESR and high
capacitance 2A current pulse will be supported. Working voltage of 3V and current consumption of 2A
define the maximum voltage drop of 0.6V (3.6V -3.0V) on the GSM transmitter working voltage.
Capacitor voltage drop calculation: V_drop = I*ESR + ∆t*I/C

Notes
• One SC replaces three high capacitance tantalums.
• Leakage current 417uA ( 3 tantalums) vs. 20uA (SC)
• Cost of Tantalum solution is much higher
31
Smart Metering Application – ISM band solution
Background:
ISM transmissions are composed of long ( 100’s milliseconds) power bursts with a current consumption of 10’s mA.
Battery voltage is 3.6V. ISM transmitter operates at working voltage of 3V when the regular
current pulse is 20-30mA. Current of 30mA can cause high voltage drop on battery due to its high internal resistance.
The solution is to connect SC or tantalum capacitor in parallel to the battery. Due to their low ESR and high capacitance
the voltage drop will be reduced dramatically. Working voltage of 3V and current consumption of 30mA define the
maximum voltage drop of 0.6V (3.6V -3.0V) on the ISM transmitter working voltage.
Capacitor voltage drop calculation: V_drop = I*ESR + ∆t*I/C
